Make more cross-browser compatible (is that even possible in IE?)

Using ExplorerCanvas does not work. getImageData() is unsupported and will not be supported. Will try FlashCanvas.

Tried using FlashCanvas (see branch). I receive an Unspecified error when trying to use it. Not sure why. Also all the features we need are only available in the pro version which costs $31 for commercial use or free for non-profit use.

Create custom FlashCanvas may be the only option
